A three-pronged approach will help to predict COVID-19 infection in healthcare workers. At the center of it all – a ring, which tracks vitals such as heart rate and temperature and alerts the user that they might be getting sick without even realizing it. The study also will determine if participants go on to develop an acute COVID-19 infection and the prevalence rate in that population. Researchers hope to better identify patterns that could predict the emergence and recovery from novel infections to prevent and contain future pandemics.
